I agree with Cornfedboy on his assessment of the sound of the Koetsu line of cartridges. The only thing I would add is that when I auditioned the Onyx Platinum and the Rosewood Signature Platinum, there were some differences. The Onyx is slightly more resolved and has a faster sound (almost more forward), and the Rosewood ( wood body ) had a slightly warm and musical balance, without any obvious sense of loss of resolution. There is no way to make a bad choice between these two. If you are unable to listen to both in your system and decide for yourself, I hope our comments will be helpful. By the way, when my audition was performed, it was with the same equipment suggested above, a Basis Mk5 and Graham 2.0 tungsten.
